Professional-Line’s Professional-Spec Scaler shocks are goal constructed as a true-to-scale, tunable efficiency choice for critical path and scale fans. Every shock is precision CNC machined from aluminum and completed with a clean inner polish for glorious damping motion. The outside of the shock physique is okay threaded for exact changes, and the entire shock is topped with a hanging blue anodized shock cap.
All Professional-Spec Scaler shocks include an x-ring decrease shock seal for the bottom potential friction and clean motion, in addition to stopping any grime from getting into the shock, or shock oil from leaking out. So as to add to the tuning choices on the Professional-Spec shocks, Professional-Line contains each a 2-piece progressive and a single-piece linear spring setup for every shock, together with 5mm prolonged decrease eyelets for these in search of that further little bit of journey. Professional-Spec Scaler shocks come largely pre-built, that means you simply want so as to add fluid and also you’re able to hit the paths.
Upon taking the shocks out of the bundle, I used to be totally impressed with the extent of construct high quality. I at all times anticipate one thing good from Professional-Line, however these shocks actually go above and past and tick all of the bins. The outside anodization and machining high quality are top-notch. The tremendous superb threads on the shock physique allowed me to regulate the shocks to precisely the fitting top, and the added o-ring on the within of the shock collar means the setting will keep in place. The general dimension and design, from the shock our bodies to the collars give the Professional-Spec Scaler shocks a really reasonable look, like that of a high-end efficiency coilover for full dimension vans. Internally these shocks are tremendous clean, which suggests decrease friction and higher general efficiency.
The shocks come largely pre-built, which suggests they nonetheless want fluid, and that’s excellent because it gave me the choice to fill with the best fluid weight for my very own rigs. Earlier than filling with oil, I might counsel including a dab of your most popular shock seal grease to the seals for good measure. The x-ring shock seal design has gained reputation over time amongst producers of efficiency RC shocks, and for good cause. The x-seal not solely helps to raised forestall grime and dirt from getting into the shock, but in addition reduces friction on the shock shaft resulting in smoother motion and higher efficiency. The two-piece progressive and single linear spring choices are additionally an amazing contact, particularly for expanded tuning.
Personally, I most popular the linear choice for my crawler rig, because it offered clean, predictable efficiency. The progressive 2-piece design excelled on my sooner rock racer, absorbing bumps and whoops like they have been nothing. It’s nice to have each choices and means the shocks can play double obligation when wanted. Total, Professional-Line’s Professional-Spec Scaler shocks are nice for correct scale builds and efficiency crawlers alike and can make an amazing addition to your path rig.
